 Let's take a look at the Get Network Devices endpoint. A Network Device transports data to/from host devices or other network devices. A network device is typically a hub, switch or router and can be connected by an Ethernet cable or can have a wireless connection. Our goal here is to find the network devices and display information about them.
 
-You can look at the details of the Get Network Device API from the -- <a href="http://devnetapic.cisco.com/" target="_blank">APIC-EM API Docs</a>.

+2. To retrieve the list of network devices, enter the information in the appropriate Postman fields, as shown here:
 	* **Method**
-		* `A.` Select **GET**.
+		* **A.** Select **GET**.
 	* **URL**
-		* ``B.`` Enter `http://{APIC-EMController}/api/v1/ticket`
-			* If you are not using your APIC-EM controller, use the Always-On APIC-EM Lab: <a href="https://devnetapi.cisco.com/sandbox/apic_em">https://devnetapi.cisco.com/sandbox/apic_em</a>.
+		* **B.** Enter `http://{APIC-EMController}/api/v1/network-device` or, if you are not using your own APIC-EM Controller, enter the Always-On APIC-EM Lab controller`https[]()://devnetapi.cisco.com/sandbox/apic_em`.
 	* **Headers**
-		* `C.` Enter the 'Content-Type' and value 'application/json'

 	* You can see that **JSON** contains the list of hosts that was returned.
 
 The output should look similar to the example. For display purposes, some records have been removed.

 ### Things to Try
-* In Postman append to '/1/2' to the call http://{APIC-EMController}/api/v1/network-device so reads as 'http://{APIC-EMController}/api/v1/network-device/1/2' . Click the **Send** button. How does the output differ?
-* Compare the change you just made in Get Network Devices API call versus the change you made in the Get Hosts call in the previous exercise of Step 7. How are they different and why?  Hint:  Check the API Reference Guide for each of these API calls.
-* In Postman change the API call 'http://{APIC-EMController}/api/v1/network-device/1/2' to 'http://{APIC-EMController}/api/v1/user'.  Press the *Send* button. How is the returned data different and what does it represent?  Hint:  Check the API Reference Guide
